Visual Fidelity for Annotative Objects in Previous Releases
You can specify that objects maintain visual fidelity when they are viewed
in AutoCAD LT 2007 (and earlier releases) with the SAVEFIDELITY system
variable.
If you work primarily in model space, it is recommended that you turn off
visual fidelity (set SAVEFIDELITY to 0). However, if you need to exchange
drawings with other users, and layout fidelity is most important, then visual
fidelity should be turned on (SAVEFIDELITY set to 1).
Annotative objects may have multiple . When visual fidelity is on, annotative
objects are decomposed and scale representations are saved (in an ) to separate
layers. These layers are named based on their original layer and appended
with a number. If you explode the block in AutoCAD LT 2007 (or earlier
releases), and then open the drawing in AutoCAD LT 2008 (or later releases),
each scale representation becomes a separate annotative object, each with one
annotation scale. It is recommended that you do not edit or create objects on
these layers when working with a drawing created in AutoCAD LT 2008 (and
later releases) in AutoCAD LT 2007 (and earlier releases).
When visual fidelity for annotative objects is not selected, a single model
space representation is displayed on the Model layout. Depending on the
setting of the ANNOALLVISIBLE system variable, more annotation objects
may be displayed on the Model layout, and more objects may be displayed
in paper space viewports at different sizes than in AutoCAD LT 2008 and later
releases.
Annotative Object Properties in Previous Releases
In an AutoCAD 2008 drawing, when an annotative block does not have its
paper orientation set to match the layout, and the block contains multiline
attributes that are based on a text style that is not set to match the orientation
of the layout, the attributes may shift positions if you open this drawing in
AutoCAD LT 2007 (and earlier releases).
Layer Property Overrides in Previous Releases
When you open an AutoCAD 2008 drawing containing layer property
overrides, overrides are not visible. The property override settings are retained
when the drawing is saved in a previous release, and are visible again when
the drawing is opened in AutoCAD 2008.
